Stainless Steel 416 vs X20Cr13
Stainless Steel · grade comparison
Stainless Steel 416 and X20Cr13 are both stainless steel grades. X20Cr13 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 275 MPa (39.9 ksi) for 416, about 53% more; tensile strength follows at 700 MPa (102 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 22% for X20Cr13, and X20Cr13 is harder (200 HB vs 155 HB). X20Cr13 is stiffer (215 GPa vs 200 GPa) and 416 runs hotter in service (650°C vs 550°C continuous). On the shop floor, 416 machines more easily (very good vs fair) and X20Cr13 sits in a lower cost tier (standard, $$) than 416 (premium, $$$).
416Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
X20Cr13Choose it when strength drives the design, or when cost is the deciding factor.
416 vs X20Cr13: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

416 vs X20Cr13 — frequently asked
Is X20Cr13 stronger than 416?
Yes. X20Cr13 has a typical yield strength of 420 MPa (60.9 ksi) against 275 MPa (39.9 ksi) for 416 — about 53% more. Tensile strength is 700 MPa (102 ksi) vs 515 MPa (74.7 ksi).
Which is cheaper, 416 or X20Cr13?
X20Cr13 is the lower-cost material: it sits in the standard tier ($$) while 416 is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 416 or X20Cr13?
416. Its machinability rates very good (80/100) against fair (50/100) for X20Cr13; for welding the order is X20Cr13 first (poor, 30/100) then 416 (poor, 22/100).
